At Spatial Insights we talk a lot about data, and the accuracy of
data. And the sources of data. And of course, the accuracy of the sources of
data. The lower the integrity of the
data, the higher the margin of error, and the lower the chances that any
insights derived are valid and authentic.
The chosen method of data collection is a critical tool in the armoury
of good data quality. And the data
collected, specifically the written description of the physical street address,
which more often than not is captured by employees with lower literacy levels,
forms the basis of any Spatial Analysis.
In order to gain any geographical insight, data needs to be
geocoded. This places each record’s location
on the map as per the physical street address of the record, in the form of latitude
and longitude.
Remember, garbage in, garbage out.
Mapmarker, a stand alone geocoding tool, automates the geocoding
process, and an accuracy hit rate is generated, which provides confidence
levels of data accuracy.
